After descriptions of the biology, ethology and ecology of sharks; shark/human interactions; and classification and species identification, each of the 18 species is profiled, with color photos and illustrations and information on morphology, coloration, teeth shape, size, habitat, diet, distribution, behavior, threat to humans, and other data. Maddalena is a marine life illustrator and curator of the Italian Great White Shark Data Bank. Preti is a marine ecologist and Polansky works in visual arts. The book is suitable for biologists and enthusiasts. Distributed in the US by Graphic Arts Center Publishing. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)
